WebNetwork Flow Algorithms. A flow network is a directed graph G=(V,E) with a source vertex s and a sink vertex t. Each edge has a positive real valued capacity function c and there is a flow function f defined over every vertex pair. The flow function must satisfy three constraints: f(u,v) = c(u,v) for all (u,v) in V x V (Capacity constraint) WebNov 26, 2024 · Network theory is the application of graph-theoretic principles to the study of complex, dynamic interacting systems.
